Predictive Capabilities Of Laminar-Turbulent Transition Models For Aerodynamics Applications, Jared Alexander Carnes 2022 University of Tennessee, Knoxville

Predictive Capabilities Of Laminar-Turbulent Transition Models For Aerodynamics Applications, Jared Alexander Carnes

Doctoral Dissertations

Laminar-turbulent boundary-layer transition has a demonstrable impact on the performance of aerospace vehicles. The ability to accurately predict transition is integral to properly capturing relevant flow physics. Traditionally, computational fluid dynamics simulations are performed fully turbulent, meaning that laminar flow is neglected. This, however, can result in errant predictions of vehicle performance as quantities such as skin-friction drag may be overpredicted. Resultingly, development of Reynolds-averaged Navier-Stokes transition models has seen significant attention over the last decades in order to model transition and realize the performance improvements of laminar flow.

In this work, the behaviors of several different transition-prediction methods are …

Graduate Research in Engineering and Technology (GRET)

A forward-swept wing is an aircraft wing configuration in which the quarter-chord line of the wing has a forward sweep. Typically, the leading edge also sweeps forward. Forward swept wing is proposed with the goal of enhancing performance and controllability during high angle of attack perching maneuvers. Data is presented from a series of XFLR5 analysis to qualify the aerodynamic effect of forward swept over a range of angle of attack from -25º to +75º. Various graphs were obtained during this analysis which indicates that the forward swept wing configuration can achieve qualitatively different low cost perching maneuvers.
